SocketStream messages doesn't send, and send after close socket.

[iliyafaramarzi]

i'm working on poco library and i want to create a TCP based program something like chatroom. I have a Server and a Client. when i use SocketStream to send messages to the server it doesn't work at the moment and send messages after the socket is closed(flush() doesn't work). i test socket.shutdownSend() it work but just for a message and after that close the socket. what should i do? is it better to use sendBytes and recieveBytes or no?
my client Code:
`int main() {
string message;
StreamSocket socket;
SocketAddress address("127.0.0.1", 8080);

socket.connect(address);

SocketOutputStream stream(socket);

while(true){
    getline(cin, message);

    if(message != "end"){
        stream << message;
        stream.flush();
    }else{
        break;
    }
}


return 0;

}`

mt server Code:
`int main() {
try {
ServerSocket serverSocket(8080);
cout << "Server started" << endl;

    while (true) {
        StreamSocket clientSocket = serverSocket.acceptConnection();
        SocketStream stream(clientSocket);

        string message;
        StreamCopier::copyToString(stream, message);
        cout << "Client says: " << message << endl;
    }
} catch (Exception& ex) {
    cerr << ex.displayText() << endl;
}

return 0;
